“I have a 680 model,which I love. I want to give my daughter a Roomba, but an upgraded model. Can anybody tell me the differences between my less expensive model and one of the higher end models ? Is it worth the extra money ? Thank you !”

• If I recall the difference was in the charging system but since we only own the 880 unit we cannot say how it compares to the 680. Check the specs.
